Abstract OBJECTIVE: To evaluate the efficacy of bismuth-based quadruple therapy as the first-line treatment for H.pylori infection. METHODS: A total of 136 patients with H.pylori related peptic ulcer or chronic gastritis were randomized into two groups: 67 patients in bismuth-based quadruple group received esomeprazole 20 mg, clarithromycin 0.5 g,amoxicillin 1.0 g,and bismuth potassium citrate 220 mg for 7 d; 69 patients in standard triple group received esomeprazole 20 mg, clarithromycin 0.5 g and amoxicillin 1.0 g for 7 d. Outcome of eradication therapy was assessed by (14)C-UBT. On ITT and PP analysis, calculating the cost-effectiveness ratio (C/E) and the incremental cost-effectiveness ratio (delta C/delta E). RESULT: On ITT and PP analysis, the eradication rates of the quadruple therapy group were 82.09\% and 88.71\%, and those of the triple therapy group were 66.67\% and 73.02\% (P<0.05). The cost-effectiveness ratio of two groups was 4.15 and 4.82; The incremental cost-effectiveness ratio of quadruple therapy group was 1.02 as against triple therapy group. CONCLUSION: Compared to the standard triple therapy regimen, the bismuth-containing quadruple therapy regimen has higher eradication rate and cost-effectiveness, which can be recommended as the fist-line treatment for H.pylori infection.
